[Intel-gfx] [PATCH v2 2/7] drm/i915: Introduce device info port_mask
Ville Syrjala
ville.syrjala at linux.intel.com
Wed May 31 13:48:01 UTC 2023
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Declare the available DVO/SDVO/HDMI/DP/DDI ports in the
device info. The other outputs (LVDS/TV/DSI/VGA) are left
out since for most of them we don't consider them as "ports".
DSI we should probably perhaps include somehow in the device
info. Just not sure how. Or we just introduce a HAS_DSI() and
call it a day?
TODO: figure out what to do about the subplatform stuff. Would
it be better to declare those directly with a different
device info or not? Also not sure the icl port-f stuff
matters even. Bspec claims there are icl SKUs with far
less ports than that and we don't seem to check for those
either?
